CrowdMaster has a Spanish translation! Featured in this v1.3.1 release is the ability to view the CrowdMaster interface in Spanish. Thanks to Christian Campos Angulo, the entire UI is supported when Blender is in Spanish mode. In addition, this release brings a number of bug fixes and smaller updates.
Thanks for using and supporting this addon!
As usual, you can get the update on the website at crowdmaster.org or you can use the integrated addon-updater module.
